Title: A MORPHABLE PACKER
Abstract:
A morphable packer and method of setting the packer in a wellbore. The packer is a tubular member having a throughbore with a central portion having a greater diameter than each end portion with tapered portions there between. Gripping elements are arranged on the tapered portions. Morphing of the tubular member creates a seal between the central portion and an outer cylindrical structure, such as a wellbore or casing, and the gripping elements are moved radially outwards to engage with the cylindrical structure. The gripping elements act as slips which are activated by morphing the tubular member. Embodiments are described with the tubular member being a sleeve on a base pipe and, additionally, sealing and securing features in the form of elastomeric bands, lugs and wedges.
